- Abstract: Objective To explore the effects of individual or combination medication of epidermal growth factor receptor tyrosine kinase inhibitor(EGFR-TKI)combined with chemotherapy on progres-sion-free survival(PFS)in advanced non-small cell lung cancer(NSCLC)patients with epidermal growth factor receptor(EGFR)mutation.Methods A total of 110 advanced NSCLC patients with EGFR mutation in our hospital from January 2019 to April 2021 were selected as research objects.Ac-cording to different therapeutic plans,they were divided into group A with 37 cases(anlotinib chemo-therapy),group B with 32 cases(icotinib chemotherapy)and group C with 41 cases(anlotinib plus icotinib and chemotherapy).The short-term effect,levels of vascular growth factors before and after treatment,and the incidence of adverse reactions were compared among the three groups.After 2 years of follow-up,survival curve was drawn by Kaplan-Meier method,and survival rate and PFS were compared in three groups by Log-rank.Results The objective response rate(ORR)was 68.29％in the group C,which was significantly higher than 43.24％in the group A and 40.62％in the group B(P＜0.05);after treatment,levels of serum vascular endothelial growth factor(VEGF),basic fibroblast growth factor(bFGF)and platelet-derived growth factor(PDGF)in the group C were significantly lower than those in the group A and the group B(P＜0.05);the total incidence of adverse reac-tions was 29.27％in the group C,which showed no significant differences when compared to 24.32％in the group A and 25.00％in the group B(P＞0.05).By the time of the last follow-up,the 2-year overall survival rate was 74.29％in the group C,which was significantly higher than 51.09％in the group A and 45.03％in the group B(Log-rank x2=6.478,P=0.039);the medi-an PFS in the group A,the group B and the group C was 9.0,8.6 and 13.2 months respectively,and differences were statistically significant(Log-rank x2=6.264,P=0.043).Conclusion For the advanced NSCLC patients with EGFR mutations,combination medication of EGFR-TKI com-bined with chemotherapy can effectively increase ORR,reduce levels of serum vascular growth fac-tors,prolong the PFS,and the safety is good.
